Formula One: Sharp-looking Alonso fastest in F1 testing

Former two-time world champion Fernando Alonso clocked the best time on the third day of pre-season Formula One testing at the Catalunya circuit on Thursday.

The Spaniard had sat out the first four-day session in Jerez earlier in February, but he continued to demonstrate he had lost none of his sharpness over the winter by taking his Ferrari to a best time of 1min 21.875sec off a total of 97 laps.

Nico Hulkenberg, in a Sauber, was second fastest with 1min 22.160sec with French driver Romain Grosjean, in a Lotus, laying down the third best time of 1min 22.188sec off 119 laps.

Alonso, the runner-up to Red Bull's Sebastian Vettel last season, improved his time from Tuesday by a second and was just a fraction off the week's best time of 1min 21.848sec set by Sergio Perez in the McLaren on Wednesday.

"The track was a lot colder than yesterday, especially in the morning. That made it more difficult to find the right level of grip," said Alonso.

"Tyre management will be crucial this season; they are softer and faster, but they also degrade a lot faster."

Germany's Adrian Sutil, competing with Frenchman Jules Bianchi for the only drive left this season -- with Force India - was eighth fastest.

Sutil, out of the sport for 15 months, improved by a second the best Force India time of the week so far set by Paul di Resta.

"This team knows me well because I spent six years with them," said Sutil.

"I wanted to show them that I am still quick and that was very important. I can sleep peacefully. I have done all I can to get back into F1. I don't know who is the favourite for the drive, it's up to Force India to decide."
